る。In the structure of the double-row tapered roller bearing 1 shown in FIG. 3, there is no particular problem, but in recent years, wheels have been supported for the purpose of reducing the number of assembly steps by reducing the number of parts. A so-called third-generation hub unit structure has been considered in which a double-row tapered roller bearing is provided integrally with a hub for supporting and fixing the wheels. When such a third-generation hub unit structure is adopted, a flange for supporting wheels is provided on the outer peripheral surface of one end of the hub body, and a first row of tapered roller bearings is formed on the outer peripheral surface of the intermediate portion. , Directly forming the first convex inner raceway. Then, an inner ring having a second conical convex inner raceway for forming a second row of tapered roller bearings is externally fixed to a small diameter step formed on the outer peripheral surface of the other end of the hub body.

On the other hand, if the seal ring is previously mounted on the outer ring, one or both of the plurality of tapered rollers and the retainer constituting the first row of tapered roller bearings incorporate the outer ring. At this time, it interferes with the seal ring, making assembly work difficult. In the case of a wheel supporting hub unit using a ball as a rolling element, the assembling work is generally performed while the ball is held on the inner diameter surface of the outer ring, so that the assembling work does not become difficult. On the other hand, in the case of a wheel supporting hub unit using a tapered roller as a rolling element, in general, the assembly work is performed with the tapered roller held on the outer diameter surface of the hub and the inner ring,
The above problem occurs. In view of such circumstances, the present invention is intended to reduce the manufacturing cost by facilitating the assembly work of a third-generation wheel supporting hub unit incorporating a double-row tapered roller bearing. It is.
